I get it . . . . French class

I've learned from another blogger that there are several scientific-sounding French words used to denote common things.

 

For example, "podotactile" describes the white strips with bumps denoting some proximity to danger, such as on the edge of the métro platform

or along the side of the crosswalk.

The transparent film on the top of a jam jar is called an l’opercule, the "cover," but apparently also is a Latin term also used to describe

And, another which means the opening in the steam iron where the water is poured, the l’orifice de remplissage.

You can learn a lot from the Internet.
